Subject: [PATCH v4 3/8] arm64: irqflags: Add condition flags to inline asm clobber list
Date:   Tue, 11 Jun 2019 10:38:08 +0100
Message-Id: <1560245893-46998-4-git-send-email-julien.thierry@arm.com>
In-Reply-To: <1560245893-46998-1-git-send-email-julien.thierry@arm.com>
References: <1560245893-46998-1-git-send-email-julien.thierry@arm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some of the inline assembly instruction use the condition flags and need
to include "cc" in the clobber list.

Fixes: commit 4a503217ce37 ("arm64: irqflags: Use ICC_PMR_EL1 for interrupt masking")
